HTTP (no SSL) sync crashes with javax.net.ssl.SSLPeerUnverifiedException

How can I solve this? I cannot import server certificate into my phone and I know the risks of using http.Thank You.

[rfc2822]

Please provide verbose logs, including the URLs that were tried to fetch. Are they http URLs?

[rfc2822]

Any news on this? Do you use OwnCloud? It redirects http to https by default, so this may be the reason.

[rfc2822]

I guess http has redirected to https, so I’m closing this.
